Just finished my build with super charger and was wondering can I at least start the engine r does it have to be tune first should you break engine I. Before getting a dyno tune

That depends a lot upon what all has been done to it. If you have put in larger injectors, guess what happens when the EEC Tells a 42lb injector (that it thinks is a 19 lb injector) to creep open enough to start the motor?

SPLOOSH!

Now all are rings have a nice gas bath.

So... what's been done to it?

Yes the injectors are bigger than 19lb Kenny Belle recommend 36lb injectors haven't bought them yet cause I don't think there big enough also have the Kenny Belle boost a pump.Just worried about putting a new built engine on a dyno without breaking it in first what u think should I take supercharger off and put stock parts back on and put a couple hundred miles on thanks for your response don't get many opinions about this really appreciate it

Probably not a good idea to mess with it until it's tuned.

It's not the supercharger that is going to wash down your cylinder walls with fuel, it's those 36 lb injectors that the EEC currently has NO IDEA what to do with.

This is the part where you have to fight with yourself to keep impatience in check.

Your motor break-in period will be pretty much over with after the first 5 minutes of idle. Some say a good long deceleration is a good idea. The point is that there's no special magic fairy dust that needs to be sprinkled onto a modern hydro roller build. If it starts and runs without leaking, sucking in unmetered air, or puking out parts, you're good.

Any good tuner will write a start up tune so you can break it in idling etc. it will not be a drive it on the street and beat on it tune.

Build it how you're going to run it and have a reputable tuner build you a start up/idle/get it on a trailer tune so you can break in the motor in your garage then take it to them (change the oil in between those two things)

Good luck. I'm balls deep in one as well right now. Check it out in the talk section and maybe it will save you from making some of the same mistakes I did.

Yeah, feel free to ask away. I'm by no means a resident expert and have learned most of my useless knowledge by trail and error. I can usually say with confidence what doesn't work.
